New York, have invented ee'rtain newanduseful Improvements in'Railway-Spikes, of

whieh the following is a -full, clear, and exaet description. r

This inveutioirrelates to an improvement in railway spikes to hold the rails in posi tion on the tics.

()ur improvement is directed mainly to a novel form of'spikeb designed to remain firmly embedded in the tie when driven home. will not loosen. or eannot he pulled out by the jarring -aetion ot' the passin; trains; hence the spreading amI overturuin; of rails is prevented, as the rails'eannot spread or turn over unlessthe .sp-il'ces give. way. The. ,l(l05t.l\'ill 1 of a spike permits it to he pulled out or to, be shifted sntlieienttv to eaitise the rails to spread or turn over.-

"lIo' rar-ry our invention into practice, we take a stripiot suitable material, steel for instance, and twist the same to 'au vdesired extent by drawin; the same through dies or otherwise. 'hile tivisjtine the material, we form a projeetingridge or fin whieh extends throughout the length'of't-he twist imparted to the strip of materiah .\l ter having formed the shank, of the spike to be, we head the. same by suitable dies, :1 .eertain portion of the shank adjacent the. head being squared and not twisted. The foregoing is'anoutline of'our invention.

\Ve will now proeeed to describeour inventiondndetail, the essential features of.

which will be summarized in the appended claims, referenee being'had to the aeeompanying drawing, forming. part hereof, wherein Figure 1 is a sectional view, partly in ele- 'ation, illustrating our improved spike as applied to a rail; Fig. 2 is an enlarged side elevation of our improved spikW-looking toward one of the nntwisted sides of the upper pait of the shank; Fig. 3 is a tional view there0f,-the section bein; taken on a line 33 in'Fig. 2: Fig. 4 is a sec.- tional view, the section being taken on a line 4 tin Fig. 2; Fig. 5 is a sectional view illustrating, a modified term of spike Fig.6 is a detail view of the lower end of in other words our improved spike' the spike illustratinga modified term of piercing point: and Fig. 7 is a detail view of the. upper portion ofthe spike provided with a plain head. i

.\s herein embodied, our invention eonsists of a spike l having a twisted shank at 2 but square and not twisted atli, the said shank being provided with a head thaving,

an annular groove 5 for the-insertionof a (law-bar. To fit the tapered flange t) of a rail'T. we provide thehead -lwith an angul-ulv' dis-posed under surfaces, the said sur- -'.iee lllelgl'lllg' into a fillet S.) at the point where the shank l and head i join. The shank l will he twisted to any'Kh-sired 'eX- tent. preferably by drawingthe' same through dies but we do not limit ourselves to this particularoperation. ()n'e of 'the features of our invention is the provision of.

p rojeeting ridfres 'or tins it) which extend throughout the twisted portion of-Ithe shank l, the said ridges or -;fin s; mergii'i'g into the eorners ll oi the'sqnzired portion] 3 of the shank. can be, seen in 'lii'g tk the, twisted" portion, 1 of the shank-leoiisists offapalf allelogram ha vine extended cor t f one side 10 of the ridge. the other side 10* of the ridge hein, angularlv disposed, relative to the adjaeent side'of the paralleld gram, to form an ohtuseangie; The. shank 1 is n'e-ferablv provided. atits lmver end, with a piercing point 12. The head 4 is provided with the annular recess to permit of the insertion of-a claw-bar to pull the spike outot the tie 13.

For reasons, which we will explain, the head 4 is preferablv made eireular although the usual spike head can he used. The cireular head is preferable for the'reason that it is not necessary to place the spike in any particular position, to bring the head in proper position upon the flange (3, when the spike is driven home. Should the ordinary head he used, it would be necessary to place the spike in a position, before being driven,

track workman, this might cause trouble and delay. By employing a round head, the positioning of the spike can be disregarded.

Our improved spike will not split the ties or will not back off due to the jarring of the track structure. When the spike is driven in, it will naturally rotate; but

' should it tend to back oil, the ridges 10 willact as an abutment. To remove the spike, a claw-bar would be inserted in the groove 5 of the head 4, but even this operation would require great force.

When our improved spike is used, the tieplates, one being illustrated by ll, will be provided with circular openings 15. The

extent of the squared portion 3 of the'shank 1 will be slightly greater than the combined thickness 0 the edge of the flange '6 and tie-plate l4; hence when the spike is driven home, a part of the squared portion 3 will enter the opening made by the spike and fill or plug said opening, w-hereby water is prevented from soaking into the tie through the opening made by the spike.

- '.Instead of forming the ridges or fins, as

shown in Fig. 4, we may form them as shown in Fig. 5, in which the fins are in gdicated by 16. In this form, the fins have Having now described our invention, what we claim and desire to secure by Letters Patent is:

1. A spike consisting of a twisted strip of material having flat sides, and ridges or fins carried by said strip located at the meetlug-edges of said fiat sides, each ridge or iin having a straight wall, said straight \\'all being a continuation of one of the adjacent fiat sides, the other wall being angular-1y disposed relative to theothcr adjacent fiat side.

2. A spike consisting of a shank, said shank being provided ,with a plurality of helically disposed channels, said channels having an obtuse angular formation, each channel terminating in a flat surface at one end of said shank; the combined flat surfaces forming a square, one wall of said channel being of greater length than the other.

3. A spike consisting of a shank twisted throughout the greater part of its length, the twisted portion forming in cross-section, a parallelogram having extended corners, providing projecting fins, the said extension of the parallelogram forming one side of the fin, the other side of each fin being angularly disposed to form an obtuse angle relative to the adjacent wall of the parallelogram, substantially shown and described.
